THE STORY
This isn't your typical "restored truck." This 1986 GMC Sierra 1500 has been transformed into a no-expense-spared, ground-up pro-touring street machine. With over 3,000 hours of labor poured into every inch of this build, the attention to detail is next-level. The entire chassis and suspension system was rebuilt using Phat Phabz's industry-leading air ride components, and the powertrain is nothing short of brutal-650HP from a brand-new LSA, backed by a built 4L80E and tough 12-bolt rear.

Every square inch of this truck screams custom-from the paint and fabrication to the polished underpinnings and finely stitched leather. It shows just as well underneath as it does on top. It's the kind of truck you could drive to SEMA, win a trophy, and then cruise home comfortably with the A/C on.

Whether you're hitting shows, cruising the boulevard, or just want to own one of the cleanest, nastiest squarebodies in the country-this Sierra checks every single box.

Turn the key, hit the air ride, and watch jaws drop. This is what a modern squarebody should be.
